Default Data Value In Gridview?

Hi,

I am trying to set a default value for a date field in my update parameters:



When I try an update with the DefaultValue="<% Now %>", I get this error:
"String was not recognized as a valid DateTime."

The updates work fine if no default value is set and it also works ok if I change the default value to a set string, such as "6/24/06".  I've tried using different data sources and datasets, but no luck.

Anyone have any ideas on this?

Thanks! <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:db1ConnectionString %>"
